I don't know very much about c.F. Yet, but I am doing some research on it for a class in college. Cystic fibrosis is an inherited condition that causes the mucus in the lungs and the digestive tract to be abnormally thick. This makes it extremely difficult for patients with c.F. To digest food, especially foods that are high in fat, and therefore, c.F. Patients do not put on weight very well, even though they might eat enormous amounts of food.
The thickened mucus in the lungs also makes it difficult to breathe at times. Another complication this mucus causes is a lot of respiratory tract infections, such as bronchitis. The mucus acts as a home for the bacteria and viruses, causing frequent and often times severe infections. It is also a progressive disease, meaning that it gets worse as tim goes on. Patients these days are expected to live about twenty-one years, up ten years from twenty-five years ago.
It is entirely treatable, though. As patrick said, embolization can help. There is no cure for c.F. As of yet, however. There is no way to prevent it, either. It is estimated that 1 in 20 caucasions carry the gene that causes c.F. It is a recessive trait, however. C.F. Can now be detected in unborn children. Scientists have found the gene that causes it, and can determine if an unborn child will have c.F. With a high rate of accuracy. If they don't catch it before the child is born, it can also be detected as early as two months in infants by a sweat test. This test is not 100% accurate-few tests of any kind are-but it is a reasonably reliable test. It works by measuring sodium levels in the sweat, as c.F. Patients have a much higher concentration of sodium in their sweat.
One of the books I am using in my research is called "robyn's book: a true diary." this book is an autobiography written by a young woman who had c.F., and was published in 1986 by a company by the name of point. It is not a very technical book; I found it in the children's literature section of my school's library, but I have enjoyed what I have read so far. You might look into maybe finding a copy.
I wish you luck in this, and I apologize if any of this information is in any way incorrect.
